“I think of a number, double it, and add twelve. My answer is 54.” What number am I thinking of?

Answers

Answer:

21

Step-by-step explanation:

21 + 21 = 42

42 + 12 = 54

so 21 is your answer

Answer:

21.

Step-by-step explanation:

For questions like this, it's easiest to work your way backwards from the answer to get the original number.

In this case, you subtract 12 from 54, which gives you 42 (54-12=41)

Then, you divide by 2, the opposite of "doubling". 42 ÷ 2 = 21.

Since there are no other operations, your original number is 21.

To confirm, just go through the problem again starting with 21 and seeing if you get to 54.

21, doubled (42), add 12 = 54.

how to solve this problem by finding x​

Answers

Answer:

X=140

Step-by-step explanation:

Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees

The attachment you are showing us shows that we already know two angles

(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360.

X+70+60+90=360

X=360-70-60-90

X=140

Answer:

$324 for 72 pints$306 for 36 quartslarger size is better deal

Step-by-step explanation:

The cost of 72 pints is 72 times the cost of 1 pint:

  72 × $4.50 = $324.00 . . . cost of 72 pints

The cost of 36 quarts is 36 times the cost of 1 quart:

  36 × $8.50 = $306.00 . . . cost of 36 quarts

__

The price for quart containers is lower, so the larger size is the better deal.

Buddy and his team have been asked by NASA to make a space shuttle cake (a scale model shaped like the one to the left) for a fundraising event. The original space shuttle has a height of 184 ft and a wingspan of 78 ft. Buddy and his team decide to construct the cake on-site so that they do not have to worry about transporting it. Buddy decides to make a cake with a wingspan of 10 ft and asks one of his decorators, Ivette, to calculate the height of the cake. Ivette decides that the cake should be approximately 4 ft tall.

Answers

Answer:

Ivette is wrong and by a lot. The spaceship should be 23.59 feet high

Step-by-step explanation:

The relationship between the spaceship's height and width = 184 feet : 78 feet ≈ 92 : 39 ≈ 9.2 : 3.9. This means that for every 3.9 feet wide, the cake should be 9.2 feet high.

In this case, the spaceship is 10 feet wide, so it should be (10 / 3.9) x 9.2 =  23.59 feet high.

When you make scale drawings or scale cakes, you must keep the same proportions as the original model.

Please help will give BRAINLIEST

Answers

Answer:

D

Step-by-step explanation:

We have the equation:

[tex]x^2+y^2+12x-10y-7=0[/tex]

And we would like to convert this to an equation for a circle.

This will require completing the square. Thus, let’s factor group our factors. We will also move the constant to the right. Therefore:

[tex](x^2+12x)+(y^2-10y)=7[/tex]

To complete the square, we divide the b term by 2, square it, and then add the resulting constant to both sides.

Therefore, for the first term, we will have 12/2. 12/2 is 6. 6 squared is 36.

Hence, we would add 36 to both sides.

For the second term, we have -10/2. -10/2 is 5. 5 squared is 25. Hence, we would add 25 to both sides.

This yields:

[tex](x^2+12x+36)+(y^2-10y+25)=7+36+25[/tex]

We can now factor the two terms using the perfect square trinomial pattern. We will also add on the right. Hence, our equation is:  

[tex](x+6)^2+(y-5)^2=68[/tex]

Therefore, our answer is D.

a case bottle water contains 24 bottles . each case contains a total of 405.6 ounces of water wich equation represents the relationship between ounces of water , y,and number of bottles,x

Answers

Answer:

y = 16.9x

where y is the ounces of water

and x is the number of bottles

Step-by-step explanation:

Here, we want to find the relationship between ounces of water y and number of bottles x

From the question, we can find the amount of liquid in each bottle

Mathematically, that will be 405.6/24 = 16.9 ounces

There is 16.9 ounces of water per bottle

So the relationship we want to write is that;

y = 16.9x

Given the diagram below. If G is the circumcenter of ABC. DC = 16, GB = 21 and AZ = 19, find each measure.​

Answers

Answer:

Step-by-step explanation:

Properties of a circumcenter;

1). Circumcenter of a triangle is a point which is equidistant from all vertices.

2). Point where perpendicular bisectors of the sides of a triangle meet is called circumcenter of the triangle.

From the picture attached,

9). AG = GB = GC = 21

10). BC = 2(DC)

            = 2×16

            = 32

11). By applying Pythagoras Theorem in ΔGFB,

     GB² = GF² + FB²

     (21)² = GF² + (19)²

     441 = GF² + 361

     GF² = 441 - 361

     GF = [tex]\sqrt{80}[/tex]

     GF = 8.9

12). By applying Pythagoras theorem in ΔGDB,

     GB² = DG² + BD²

     (21)² = (DG)² + (16)² [BD = DC = 16]

     DG² = 441 - 256

     DG = √185

     DG =  13.6

Solve for x in y = -4x + 6.

If there are 52 calories in one chicken nugget and 39 calories in one waffle fry, write an expression to represent the total number of calories consumed if you eat c chicken nuggets and w waffle fries. Next, find out total number of calories consumed if you ate 5 chicken nuggets and 10 waffle fries.

Answers

Equation: y = 52c + 39w
Plug in 5 for c and 10 for w
52(5) + 39(10) = 260 + 390 = 650 calories

Multiply calories per nugget by number of nuggets and add to calories per waffle multiplied by number of waffles:

Total calories = 52c + 39w

Now replace the variables with the quantities and find total calories:

Total = 52(5) + 39(10)

Total = 260 + 390

Total = 650 calories
